There are 5 EN(s) today, 2 associated with power stations.

[ One of the ENs is a repeat of yesterdays Farley EN. ]

----------- [ Current event for AL_Farley_1 ]

20180508 | AL_Farley_1 | CONTAINMENT LEAK RATE GREATER THAN TECH SPEC |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53393
RFOD_029; RX Mode: Hot Standby ; Hot Standby

"On May 8, 2018 at 0139 Central Daylight Time, Farley Nuclear Plant Unit 1
declared containment inoperable due to total containment leak rate greater than technical specifications.

The 1B containment cooler had seat leakage of approximately 30 gallons per minute from a service water drain valve.

"Though the containment cooler service water supply is not tested per the Appendix J program,
a loss of the containment barrier is possible under accident conditions.

"The service water flow path to the 1B containment cooler has been isolated to exit the condition."

The licensee will notify the NRC resident inspector.

-----------

Appendix J to Part 50—Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors
https://www.nrc.gov/reading-rm/doc-colle...-appj.html

These test requirements provide for preoperational and periodic verification by tests of the leak-tight integrity of the primary reactor containment,
and systems and components which penetrate containment of water-cooled power reactors, and establish the acceptance criteria for these tests.
